Fiber posts are often used to treat large coronal material defects during endodontic treatment when the crown no longer provides adequate support, especially before indirect restorations are performed. In their recently published meta-analysis, Alenezi et al. investigated the effects of fiber posts on clinical success and survival in endodontic treatment.
This study analyzed 17 different clinical studies involving 7,278 endodontically treated teeth, totaling 7,330 teeth. The results showed a significant improvement in the survival of teeth restored with posts. The authors concluded that post placement improves the clinical performance and survival of endodontically treated teeth.
RTD (Dentsply Sirona, headquartered in France) is an innovator in the field of fiber posts. Founded in 1968, RTD was one of the first companies in the world to invent and patent fiber posts. Since then, RTD has continued to innovate fiber posts.
Other fiber posts on the market may have uneven fiber distribution or even air bubbles in the resin; RTD has optimized its products for fiber posts in endodontics to eliminate these potential post weaknesses and thus the weak points of the coronal restoration.
The DT Light post, with its typical double taper design, is RTD’s most famous product. Compared to single taper or parallel posts, its shape helps to better distribute stress and conform to the natural geometry of the root canal, thereby reducing the amount of dentin removed, especially in the apical third, where unnecessary dentin removal increases the risk of fiber post fracture during endodontic treatment.
